APPLICATION FILED SEPT. 19. 1913.

FL 9 lfififi Patented Apr. 25, 1916.

WVEEA a LA products of combustion can escape from the chamber. The upper end of the discharge pipe connects withone or more expansion nozzles 16 which direct'the gases upon the buckets 17 of the turbine 18. 'The centrifugal force due to the whirling motion of the contents of the chamber throws the ashes and unconsumed fuel against the walls of the chamber where they drop into the pockets 19 formed in the bottom of the bottom of pipe 21 r ms down to a receiver 22 in which the ash-2.; and other refuse collect. The pipes F31 and receivers 22 are preferably watqr-jacketed, as shown, and each pipe can valves 23 when the out through'the manhole 24.

n accordance with the provisions of the 25 'ent statutes I have herem out by other means.

What Ijclaim as new and desire to secure by Letters Patent of the United States, is pparatus for burning powdered fuel,

into said chamis b thetop thereof, at a tangent'near and a receiving chamber. 3. In an apparatus of the character decombination of a circular scribed, the casthe fuel h pocket is an opening 20 from which a the fuel said chamber,

the fuel at a tangent bustion chamber,

ing, a discharge conduit extending from the upper end of the casing to a point adjacent the lower end thereof thereby forming with the casing an annular combustion chamber, means for blowing fuel into said annular combustion chamber adjacent the top thereof and at a tangent thus setting up a whirling movement of the contents of the chamber, and means forming pockets at the bottom of the chamber;

Apparatus for binning powdered fuel, comprising a circular combustion chamber having a conical top, means for blowing in at a tangent near the upper end of said chamber, and a central discharge pipe passing up through said top.

0. pparatus for burning comprising a circular aving a conical top, at a tangent powdered fuel, combustion chamber means for blowing in near the upper end of central discharge pipe passing up through said top and extending own nearly to the bottom of said chamber. 6. Apparatus for burning powdered fuel, comprising a circular combustion chamber having a conical top, means for blowing in near the upper end of said chamber, a central discharge pipe passing up through said top and extending down nearly to the bottom of said chamber, and a water jacket for said pipe.

against the Walls trifugal force, pockets at the bottom of the chamber to'receive the refuse or ashes, and receivers connected to said pockets.

In gvitness whereof, I have hereunto set my hiind this the sixteenth day of September, 1913.
